AD8055ANZ from Analog Devices, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No connect; not internally connected per the N-8/R-8 connection diagram.
2	-IN	input	Inverting input of the AD8055 voltage feedback amplifier; differential input voltage limited to ±2.5 V.
3	+IN	input	Noninverting high-impedance input (10 MΩ, 2 pF) with input common-mode range of 3.2 ±V typical at ±5 V supplies.
4	-VS	power_in	Negative supply; operating range ±4.0 V to ±6.0 V (±5 V typical), 13.2 V maximum total supply.
5	NC	unconnected	No connect; not internally connected per the N-8/R-8 connection diagram.
6	VOUT	output	Amplifier output, delivering over 60 mA load current with short-circuit current of 110 mA typical.
7	+VS	power_in	Positive supply; operating range ±4.0 V to ±6.0 V (±5 V typical), 13.2 V maximum total supply.
8	NC	unconnected	No connect; not internally connected per the N-8/R-8 connection diagram.
